To all whom it may concern:

Be it known that I, PEDRO VIDELA, a citizen of Chile and a resident of Santiago, in the Province of Santiago, Chile, have invented a new and Improved Hydrauli Motor, of which the following is a full, clear, and exact description.

This invention relates to motors and par ticularly to a hydraulic motor in which a maximum power is secured from a given quantity of water having a given fall.

The object in view is to provide an improved construction in which a plurality of turbines are connected to a single supply and are acted on successively by the water from said single supply until substantially all of the power has been secured therefrom.

V Another object in view is to provide a mo tor structure with an arrangement of turbines havingtheir casings connected up and stand pipes associated therewith for maintaining a head of water for each turbine from a single source in order to secure a maximum effort from a given supply of water having a given fall.

A still further object of the invention,

Q more specifically, is to produce a turbine in which power may be extracted from the wav ter passing therethrough and the out-go caused to operate one or more succeeding tur-' bines in a similar manner.

In the accompanying drawings:

Figure 1 is a side view of a hydraulic motor disclosing an embodiment of the invention. Y

Fig. 2 is a side view on an enlarged scale of the lower part of the structure shown in Fig. 1, certain parts being broken away for better disclosing the construction of the easin and'turbines arranged therein.

Ti re 3 is a sectional view through Fig. 2 on he 3-3, the same being on a slightly reduced scale.

i Fig. 4 is a section through Fig. 2 on line Fig. 5 is an end vlew of the structure shown in Fig. 3, the stand pipes being shown in connection therewith.

Fig. 6 is a detail fragmentary sectional view through the thrust hearing at the outlet pi e.

Ref rring to the accompanying drawings by numerals, 1 indicates a sluiceway or pipe of any kind for guiding a supply of Water to the receiving box or tank 2, which receivlug box or tank is connected with a stand pipe 3 and in free communication therewith so that the stand pipe 3 is always maintamed full of water as long as there is a suflicient supply in the tank 2. The pipe 3 extends downwardly and is connected to the casing of the turbine 1, while stand pipes 5, 6, 7 and 8 are connected to their respective turbines 9, 10, 11 and 12. Preferably there are a plurality of turbines and a stand pipe for each one, there being five turbines shown in the drawings, turbine 4 acting as the intake turbine while turbine 12 acts as the outlet which discharges into the outlet pipe 13 and from thence to the discharge pipe 14 which leads to any suitable discharge tank. A shaft 15 is mounted in suitable bearings 16 and 17 and extends through all of the turbines so asto be driven by the various turbines when the device is in operation. The bearing 17 is preferably a thrust bearing, as shown in Fig. 6, in which a removable wearing plate 18 is provided against which the member or foot 19 presses. An adjusting screw 20 presses against the member or foot 19 so as to move the shaft 15 longitudinallyin one direction whenever desired.

The various turbines 4 and 9 to 12 inclusive, are identically constructed so that a description of turbine 4 will equally apply to the remaining turbines. Referring more particularly to Figs. 2 and 4, the turbine 4: is provided with a casing 21 of any suitable kind which has supporting webs 22 and 23 resting on supporting bars 24: and 25. A discharge outlet 26 is provided at the bottom of casing 21, said outlet being normally closed by a plate 27 which may be held in place by bolts or other means and may be removed when it is desired to clean or secure access to the turbine. Connected to shaft 15 by a key or any other way desired is an impeller or power member 28 which is provided with a plurality of blades 29 formed substantially on the lines of an ogee curve. These blades are inclined in one direction, as shown particularly in Fig. 4, and coact with the standard guide blades 30 on the fixed or stationary rings 31 so that the water may exert its full power on the blades previous to the entrance of the water into the outlet or eye 32 of the impeller, which outlet discharges into the tubular connection 33 (Fig.

2 which tubular connection connects the casing of one motor to the motor.

From this it will be seen that -the waterpassing downwarclly through pipe 3 enter casing 21 and entirely surround the impeller 28 at some little distance therefrom and will pass through the valve members 34'" mounted on the rotatable rings 35 and be guided by the blades 30 so as. to strike blade '29-and will pass between said blades evenly and discharge through the outlet or eye 82. The movement of the impeller 28 is preferably slow so as to absorb more of the energy of the water, but the water passes throughthe first turbine'with a considerable pressiire which is" not absorbed and enters'the V casing of the turbine9 and fills said casing and-the stand pipe 5 to practically thecenter of the glass gage 5'. This causes a reacting pressure "on the impeller or rotary member forming part of theturbine 9 sothat some additionalpower will be. transmitted to the shaft 15. After the water;

passes through the turbine 9 it enters the casing of turbine IOaIfd fills said casing and the stand pipe 6 to the center'of the gage'6. The water acts on the successive turbines in a similar manner so that the headwater in stand pipe?- will be approxi-" mately at the center of the gage 7 while the'head of the-water in the stand pipe 8 willbe only slightly above the casing of the turbine. From this it will be observed that the head of water in the respective stand pipes '3 and 5 to 8, inclusive,will be less'and less, the head of Water in "the re-' spective pipes assuming. an angle,v as indicated by a line drawn through the. center of the various gages 3" to 7 In case it should be desired to shut off any part of the supply'of water the rings 35 are rotated somewhat so thatthe valve members 34 will close to a greater or less:

extent the openings between the guiding plates 30. Thisis accomplished by having a link 36 pivotally connected to the rings by a suitable pin "37 preferably passing: v through both rings, as shown in Fig.2; Link 36 is also" pivotally connected at 38 "to the head 39 which head is-connectedto-the: threaded bar AO'arTangedinthe guide llz f The bar eo'e'x'tends to a pointexteriqrly of its the casing1,jasshown-in Fig. 4E, and has a hand wheel 42 'inouiited' thereon}, said fhand wheel-being "provided with "a hiib 43' "hav mgja threadedbore fitting the threade'd'bar "4o s d-as remove shat-smack and forth Rwan a-army: ti sa 44 a alges the hub 43 are raw said groove oneor' 'moreI pro-ject-ioiis' 45am arranged arthe a ley the whee14 2 together with'hub 43 may freely rbtatebut cannot move longi tddinally; massa ing a iea imamai move 6 5 ment of the shaft 40. A hand Wheel 42 and associated parts are connected with each of the motors 9 to 12, inclusive, as well as ffidtiif, so that the various motors may 'beadjustedas preferred.

In operation, it is evident that when an ample supply of water is provlded 1n the stand pipe 3 and the water is forced through the impeller or rotary member 28 a certain amount of the energy will be transmitted to shaft 15 while the remaining energy will be dissipated by the water discharged from said impeller unless otherwise utilized, By arranging a plurality of turbinesjin line and providing casings and stand pipes as described, this unutilized supply of water -isca'used to operate these additional turbines until the entire full head. of waterhas been fully utilized, which naturallysh'ows a decided increase in power secured from-the water over the powersecured from a single turbine. It is evident that a largerfnumber or a lessnumber of stand pipes andmotors could be associated together for a given supply of water without departing from-"the spirit-"of the invention, but by experiment it "has beenfou'nd-that five motors will usually ab'sorbfall of theenergywhichwill be pro- :ducedby the fallof water, especially when the "parts, arearranged as shown, which causes the :fiveturbines together to produce", practically"threejtiines the power'fof the first tnrbine by reason of :the' distributionof the energy of thewatr in-passing through "the entire construction; This construction: and
